"Could a father not marry his son?" Irons asked HuffPost Live host Josh Zepps. Irons argued that "it's not incest between men" because "incest is there to protect us from inbreeding, but men don't breed," and wondered whether same-sex marriage might allow fathers to pass on their estates to their sons without being taxed.

There could very well be a Donald Trump joke in there somewhere.

"It seems to me that now they're fighting for the name," Irons said of advocates for same-sex marriage as opposed to civil unions. "I worry that it means somehow we debase, or we change, what marriage is. I just worry about that."

Really? Does he, you know, stay up at night, worrying about that?

Irons said he "(doesn't) have a strong feeling either way" on same-sex marriage, and he "(wishes) everybody who's living with one other person the best of luck in the world, because it's fantastic."

"Living with another animal, whether it be a husband or a dog, is great," he said. "It's lovely to have someone to love. I don't think sex matters at all. What it's called doesn't matter at all."

Irons also ripped New York City Mayor Michael Bloomberg over the proposed restrictions on soda, describing himself as a "complete libertarian" and likening Bloomberg's policies to a "nanny state."
